Shawn, I just tried to have the co-op enabled on 6 sites, all the sites are on the same server and would appear to make the request for the ad from the same IP: 66.**.*.* Did the co-op server lock out that IP on account of too many requests? If so it resulted in taking down all 6 sites because the script still lacks a timeout feature. 1) Can you clear the IP? 2) Is the preferred method for enabling 6 sites on the same server, to share 1 ad_networks.php and ad_network_ads.txt file? 3) A timeout really needs be added to the script. The current script protects the DP server put does nothing to protect the sites running the script.
Hmmm... Thanks, maybe the host has some sort of adaptive firewall then. The ads were coming in fine and then all of the sudden no response when attempting a call to the DP server. When you do block an IP do you send back an error message? Is the preferred method for enabling 6 sites on the same server, to share one ad_networks.php and ad_network_ads.txt file? Or does it not matter?
A IP block will send an email first when I get around to coding it. Right now, it just blocks it (no email). But your IP was never blocked at any point. It's always preferred to have as few requests to the ad server as possible, so if your setup allows you to share the ad_network files between all sites, that would be ideal.
